Mongolian Tree Ring Chronology from 445 to 44 BC

Tree ring width data from the Manzshir Hiid site in Mongolia provides a 489-year climate proxy record. The National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information archived this paleoclimatology study. Data was last updated in the repository in January 1994.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Eastern Asia using annual tree ring width variations.
• Calibrate regional climate models by comparing the 489-year tree ring chronology with other proxy records.
• Analyze growth response and climate sensitivity of the sampled tree species (PISI) at the Mongolian site.
• Study long-term ecological trends and potential extreme events within the calendar years before present (BP) timeframe.

Strengths

• 489-year continuous chronology from 445 to -44 calendar years BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's temporal coverage ends 44 years before present, lacking modern calibration.
• Sample size, species details, and replication depth are unknown from the provided metadata.
• Data is stale, with no updates to the repository record since 1994.
